i dont think nen can be "used up," the consequences of the deal he made with himself to transform his body were far more significant than losing his nen
no matter what his reasoning for not using, or rather; releasing his Nen was the first two times the fact of the matter is
he didnt use it
this "meditating" as you call it is actually, practicing Ten the art of keeping the aura from leaking away from his body
he was told by both wing and biske to practice to practice Ten every day why do you think that is?
anyway a single 1/3 page picture and the text "my aura isnt coming out" is hardly enough to make a concrete answer out of just my theory
The way I see it is like this:
Celestial Tower: Allowed to practice Ten (I know I said Ren the first time, mixed up the words), which basically means practice the core of Nen. Not really strange he looked a lot stronger when he could finally use Ren after months of Ten-training a short while after he had just "unlocked" Nen.
After going bankrupt: Forced Zetsu, he couldn't train any Nen during the time, except maybe mental training (that's what I mean with meditating), but when he got out of it he was fully rested compared to when he had been practicing Ren and fighting Knuckle every day. Don't really find it strange that he looked a lot stronger.
Not saying you're wrong, but I doubt this loss and retrieve of Nen is going to make him stronger without any other cause than "storing up".
